  2. Alligation Percent concentration based questions Let x litre of a% acid is mixed with y litre of b% acid. Let concentration of final mixture be z%. When we mix two liquids we have following conclusions Conclusion 1: Volume of final mixture is sum of the two mixtures. Conclusion 2: Concentration of final mixture is unknown but it will lie between the two concentrations a and b. Let a > b, hence a > z> b.
